Question

Most of the worlds deserts are located at latitudes where

A) hot, dry air moving toward the poles descends.

B) hot, dry air moving toward the equator rises.

C) cold, dry air moving toward the equator descends.

D) hot, dry air moving toward the poles rises.

E) cold, dry air moving toward the poles descends.

Answer 1

The formation of Deserts

Deserts occurs in 2 broad belts, at 20-30o north and south of the Equator, along the Tropics of Cancer and Capricorn. Desert areas develop under the influence of the quite permanent high-pressure areas.

Desert Soil Formation

Desert soils are downright unusual! They vary tremendously in texture; many are sandy and gravelly, while others contain layers of sticky clay, or even rock-hard, white limy layers. Desert soils may be gray-colored, brown, or even brick red.

Overview of the Desert

The word desert brings to mind powerful images for many people. Some believe a desert to be a hot, barren place without surface water. Others think of a desert as a dry region covered with sand dunes and tall, branching cacti that resemble human forms. Actually, neither of these images is completely correct.

Deserts

This site has a list of links on deserts that explain what deserts are and how they form.

Types of Deserts

Deserts are classified by their geographical location and dominant weather pattern as trade wind, midlatitude, rain shadow, coastal, monsoon, or polar deserts. Former desert areas presently in nonarid environments are paleodeserts, and extraterrestrial deserts exist on other planets.

Wind Action and Deserts

Wind is common in arid desert regions because:

1. Air near the surface is heated and rises, cooler air comes in to replace hot rising air and this movement of air results in winds.

2. Arid regions have little or no soil moisture to hold rock and mineral fragments.

Wind has the ability to transport, erode, and deposit sediment. In this lecture we will discuss each of these aspects of the wind.

Answer 2

B) hot, dry air moving towards the poles descends.

These latitudes, around 30°N and S, are called the Horse latitudes.

Answer 3

If you mean most of the desert area, the answer is E. Antarctica is the biggest, driest desert on Earth with more area than the rest of the world's deserts combined. Air sinks at the south pole, and the wind blows in all directions away from the pole.

Answer 4

A) hot, dry air moving toward the poles descends.

Answer 5

Answer 'C'.

All the major 'hot' deserts of the world are located in central/western side on continents between latitudes 15 degrees and 30 degrees North and South of the equator.

A notable wind feature of them all the the 'Trade' winds, which blow north easterly and south easterly, in the northern and southern hemispheres respectively.

The main deserts are:- .Mojave, Sahara. Arabian and Baluchistan in the northern hemisphere, and Atacama, Kalahari, and Australian in the southern hemisphere.
